Massive Long Run

This is what I'm in the mood for. This morning, I calculated all my training paces for a Boston BQ, using the Runner's World advanced plan. Just looking for speedwork ideas and general weekly structure. My mile PR is called my 'cruise' pace! This is gonna be tough, but I think I can pull it off. Next question to answer for myself is, where can I find a reliable track environment? I'll do a google flyover of the terrain between here and work, first of all. Baystate is 13 weeks away!
